A thrift is a kind of bank that arranges mortgages (mostly for home ownership) and sets up accounts to receive deposits.
The statement is actually false. The difference is in who they can borrow from and whether or not they are set up for profit. Thrifts are usually non profit.

The equation 4x² + 12x + 9 = 0 has exactly one solution. The correct answer would be an option (C).
What is a quadratic function?
The quadratic function is defined as a function containing the highest power of a variable is two.
The solutions to a quadratic equation are found using the quadratic formula, which is:
x = (-b ± √(b² - 4ac)) / 2a
As per option (C),
4x² + 12x + 9 = 0
Compare the given function to the standard quadratic function f(x) = ax² + b x + c.
We get a = 4, b = 12, and c = 9.
The discriminant of the equation,
b² - 4ac = (12)² - 4×4(9) = 144 - 144 = 0
Since the discriminant is zero, this means the equation has only one solution.
Therefore, the equation 4x² + 12x + 9 = 0 has exactly one solution.
Hence, the correct answer would be option (C).

quadratic formula: (-b(+or-)√(b^2-(4ac)))/2a.
You find that the equation 4x²+12x+9=0 only has the root of x=-1.5.
Since the solution is where the parabola crosses the x-axis, you can also figure out which equation has only one solution by whether or not the axis of symmetry lands is a solution or not. If the axis of symmetry is a solution, the function only has one solution (that being the vertex). If the axis of symmetry is not a solution, the function has to have either two or no roots. You can find the axis of symmetry by using the equation x=-b/2a. Using that equation you can find that the equation 4x²+12x+9 has the axis of symmetry being at x=-1.5 which means that the vertex is (-1.5,0). Since the equation 4x²+12x+9 has its vertex at (-1.5,0) and the vertex is the lowest or highest point of the function, that function only has one x-intercept meaning it only has 1 solution.
